Problem with ADF security and task flow calls

Question

Hi.
I am using JDeveloper 11.1.2.0.0.
I encountered a problem when tried to apply ADF security to my application.
The way to reproduce the problem:
1. Create new Fusion Web Application;
2. Import Business Components from Tables from any existing schema and add at least one table to the ApplicationModule.
3. Create "welcome page" (for instance, welcome.jsf). Add a button with fixed action outcome "test".
4. Create test page, for instance, test.jsf. Drag and drop any view object from Data Controls onto the page and create a form with navigation controls. Add a button with fixed action outcome "return".
5. Create bounded task flow, name it "test", drag and drop our test page on it - the page will be the default activity. Add a task flow return activity. Add a control flow case from the default view activity to the return activity, set From Outcome property to "return". So our return button should cause the task flow to exit.
6. Open adfc-config.xml in diagram mode and place our welcome page on it. Then drag and drop the test task flow to create a task flow call activity. Add a control flow case from welcome page to task flow call activity, set the From Outcome property to "test". So our test button should call the test task flow.
7. Configure application to run the unbounded task flow starting with Welcome view activity.
At this point all works as expected: when application runs, the welcome page is displayed with test button. Pressing the test button results in displaying the test page, return button leads back to the welcome page.
Now let's configure ADF Security.
Run the ADF Security configuration wizard, choose ADF Authentication and Authorization.
On the second page select Form-Based Authentication, check the Generate Default Pages flag.
On the third page choose No Automatic Grants.
On the next page keep the Redirect Upon Successful Authentication unchecked. Press Finish.
Open jazn-data.xml to configure roles, users and resource grants:
1. Create application role test-role.
2. Grant the test-role privileges to view the test task flow.
3. Create user and grant him the test-role.
Now we have the public available welcome page and the test page with restricted access.
When application runs, the welcome page is displayed as expected. Pressing the test button redirect us to auto-generated login page. After successful authorization the test page is displayed. But nothing happens if we click now the return button for the first time. When we click the return button once more, the application crushes with Error-500 and message "Target Unreachable, identifier 'bindings' resolved to null". The exact error trace depends on UI control bindings, but looks like this:
javax.el.PropertyNotFoundException: //C:/Users/DUDKIN/AppData/Roaming/JDeveloper/system11.1.2.0.38.60.17/o.j2ee/drs/Test1/ViewControllerWebApp.war/test.jsf @10,120 value="#{bindings.Id.inputValue}": Target Unreachable, identifier 'bindings' resolved to null

(the rest of lines skipped).
Any suggestions?

The welcome page is public available since it does not have appropriate PageDef file.
Login page comes not from the welcome page, it comes after attempt to access the test page. So after the login succeeded the test page appears, because redirect to welcome page after successful login is not configured. I do not need to return the welcome page at this moment, I need to go to the test page.
It seems the task flow call stack to be destroyed after redirect to login page.
